The invention relates to a hydrostatic drive (1) and to a method of braking a hydrostatic drive (1). In the hydrostatic drive (1), in a closed circuit a hydraulic pump (3) is connected by a first and a second working line (11, 12) to a hydraulic motor (4). The hydrostatic drive (1) comprises a brake actuation device (37) as well as at least one pressure relief valve (26, 30), which is connected to the working line disposed downstream of the hydraulic motor (4). The hydraulic pump (3) upon detection of an actuation of the brake actuation device (37) is adjustable to a braking delivery rate. The hydraulic motor (4) is adjusted in dependence upon the actuating intensity of the brake actuation device (37) in the direction of a larger absorption volume if the actuating intensity of the brake actuation device (37) increases.

The invention claimed is: 1. A hydrostatic drive comprising:a hydraulic pump;a hydraulic motor, which is connected to the hydraulic pump in the closed circuit by a first working line and a second working line;a brake actuation device; andat least one pressure relief valve, which is connected to one of the first working line and the second working line disposed downstream of the hydraulic motor, the at least one pressure relief valve being configured to open at a defined pressure value;wherein the hydraulic pump upon actuation of the brake actuation device is adjustable to a braking delivery rate and the hydraulic motor is adjustable in dependence upon an actuating intensity of the brake actuation device with increasing actuating intensity in the direction of a larger absorption volume; andthe braking delivery rate of the hydraulic pump is a delivery rate different from zero, at which the hydraulic power at an opening pressure of the pressure relief valve corresponds to an available brake power of a drive motor.
